Rather than trying to be T-shaped, I think it is better to be curious and follow up learning paths on those innate feelings for exploration. Maybe your skill set becomes fractal looking. I think this can be the basis for unique value creation. (E.g. the typography course Steve Jobs did as a student, leading to care/attention to fonts on the early Macs). I do agree with the basic idea of being T-shaped, however. I've personally seen project teams having fragile delivery capability due to a lack of skills, or lack of skill overlaps, which made the team reliant on individuals that could be off sick, on vacation, or assigned elsewhere.
